ANVIL.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application tiled March 18. 1907. Serial No. 363,099.

To all whom it may concern: l

Be it known that I, HUBERT EDWARD l SHEWARD, a subject of the King of Great Britain, residing at Protea, Fox Hill, Upper l Norwood, county of Surrey, England, have I invented certain new and useful Improvements in or Relating to Anvils, of which the following is a specification.

This invention relates to anvils, the objects being to render the working or wearing surface of a greater degree of hardness and of greater durability, and to strengthen the body of the casting, thereby minimizing de' fects in the casting and reducing fracture and breakage.

filiere chilled iron is employed in the production of anvils, the methods adopted tend to equalize the depth or extent of chill with the result that the brittleness is minimized. The construction of the anvil however is such that the supports in the end and the horn are suiiicient should fracture of the anvil occur while the same is in use to hold it together.

Now the present invention is designed with a view to 'obviating or minimizing the defects incidental to cast iron anvils as heretofore produced and particularly in regard to brittleness, softness and weakness hereinbefore referred to, and will be clearly understood from the following description aided by the accompanying drawings in which Figure l. is a plan of anvil. Fig. 2. is a 'section through the lines c aJ of Fig. l. F ig. is a side elevation of an anvil.

For the purpose of my invention, I core out the casting so as to equalize as far as possible the thickness of the metal constituting the wearing surface, and I chill the whole or a part of the working surface in the well known manner. Additional strength is hereby insured while the degree of hardness isv equalized. As a support to the casting so constituted and as affording additional strength thereto, rods, bars, ribbons or bands l of any high class metal having their surfaces jagged or c'ut, are inserted in the molds so as to extend from the cored out portion into the horns 2, ends 3, or sides 4, the said rods, bars, or the like l when the metal is poured, being rigidly united to the metal of the anvil 5 or casting. In other words, the skin of the rods, bars or the like l is fused or joined with the metal pertaining to the casting 5, and thus reinforcing the weak part of the casting care being taken not to injure the rods, bars or the like as regards their strength. By thus constructing the anvill or casting 5, considerable strength and long life are imparted thereto. A great economy in the cost of production of anvils possessing the required strength and hardness is effected, and if the core chamber be filled with metal particles or chips which may be in the form of borings, iilings, turnings 6 or otherwise, weight and solidity may be imparted to the casting; the said filling 6 being preferably mixed with a suitable binding material such as cement, and be held therein by cement 7. The aforesaid filling 6 is also effective in offering an additional support for the rods, bars. or the like.

What I do claim and desire Letters Patent is zl. An anvilY of the class described, comprising a hollow body, and a filling of cement and metal particles, within the hollowed portion of the body.

2. An anvil of the class described, comprising a hollow body, a mass of metal particles in the hollow of said body, and means for holding the metal particles in said hollow.

3. An anvil having horns comprising a body having a core of metal particles and cement, and reinforcing members embedded in the horns of the body to strengthen the same.

4. An anvil comprising a body having a working lface partially or entirely chilled, a core of cement and metal particles in the to secure by body, and reinforcing members'embeddedy in the body to strengthen the latter.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
